Which of the following is NOT a requirement for egress doors?

The requirement that an egress door must have a sliding mechanism is not a standard criterion in building codes for egress doors. Egress doors are primarily intended to provide a safe exit in case of an emergency, and their design should facilitate this function.

Egress doors typically must be side-hinged to ensure that they quickly and easily swing open in the direction of egress, allowing occupants to exit rapidly. Additionally, they must have a clear width of at least 32 inches to accommodate individuals and large items that may need to be evacuated. Furthermore, egress doors are required to provide a minimum clear opening height of 78 inches to ensure that people of all sizes can escape safely without obstruction.

The sliding mechanism, while present in some door designs, does not meet the fundamental safety and accessibility requirements that are crucial for egress doors. Therefore, it is not categorized as a requirement for egress doors.
